Can you once ensure that the sub domain “” and both “” are added to the Domains under your App.

Once you add them and configuring the CNAME record of the sub domain with the APP’s URL (“”), should resolve the issue.

Give it sometime, after you add all these for the DNS propagation. Keep us posted!
